前提条件：

将Centos6.2 二章光盘挂载拷贝到/var/ftp/pub/centos/6.2/下

[root@server Packages]# du -sh /var/ftp/pub/centos/6.2/

5.4G    /var/ftp/pub/centos/6.2/

一、安装TFTP

[root@server ~]# yum -y install tftp-server

[root@server ~]# vim /etc/xinetd.d/tftp

service tftp

{

        socket_type             = dgram

        protocol                = udp

        wait                    = yes

        user                    = root

        server                  = /usr/sbin/in.tftpd

        server_args             = -s /tftpboot

        disable                 = no

        per_source              = 11

        cps                     = 100 2

        flags                   = IPv4

}

[root@server ~]# service xinetd restart

[root@server ~]# chkconfig xinetd on

[root@server ~]# netstat -ln | grep :69

udp        0      0 0.0.0.0:69                  0.0.0.0:*  

[root@server ~]# mkdir /tftpboot/centos6.2 -p

[root@server ~]# cp /var/ftp/pub/centos/6.2/images/pxeboot/* /tftpboot/centos6.2/

[root@server ~]# cp /var/ftp/pub/centos/6.2/isolinux/* /tftpboot/centos6.2/

[root@server ~]# yum -y install syslinux

[root@server ~]# cp /usr/share/syslinux/pxelinux.0 /tftpboot/

[root@server ~]# mkdir /tftpboot/pxelinux.cfg

[root@server ~]# cp /tftpboot/centos6.2/isolinux.cfg /tftpboot/pxelinux.cfg/default

[root@server ~]# vim /tftpboot/pxelinux.cfg/default

#default vesamenu.c32

default linux

……

label linux

  menu label ^Install or upgrade an existing system

  menu default

  kernel centos6.2/vmlinuz

  append initrd=centos6.2/initrd.img ks=http://192.168.10.254/ks_centos6.cfg 

[root@server ~]# chmod 755 /tftpboot/pxelinux.cfg/default

二、配置DHCP

[root@server ~]# yum -y install dhcp

[root@server ~]# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf

[root@server ~]# vim /etc/dhcp/dhcpd.conf

option domain-name "maidi.com";

option domain-name-servers 192.168.10.254,202.106.0.20;

default-lease-time 600;

max-lease-time 7200;

next-server 192.168.10.254;

filename "pxelinux.0";

subnet 192.168.10.0 netmask 255.255.255.0 {

  range 192.168.10.10 192.168.10.20;

  option routers 192.168.10.254;

}

[root@server ~]# service dhcpd restart

[root@server ~]# chkconfig dhcpd on

三、配置NFS/HTTP

[root@server ~]# yum -y install httpd

[root@server ~]# mv ks_centos6.cfg /var/www/html/

[root@server ~]# yum -y install nfs-utils

[root@server ~]# cat /etc/exports 

/var/ftp/pub/centos/6.2/ *(ro)

[root@server ~]# /etc/init.d/rpcbind restart

[root@server ~]# /etc/init.d/nfs restart

[root@server ~]# /etc/init.d/httpd restart

四、配置Kickstart

[root@server ~]# yum -y install system-config-kickstart
